JOHN RAYNALD, OF PHILADELPHIA, PENNSYLVANIA.

FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 438,895, dated October21, 1890.

Application iiled May 16, 1889. Serial No. 310,998. (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN RAYNALD, a citizen of the United Sta-tes, and aresident of Philadelphia, Pennsylvania, have invented certainImprovements in Fountain-Pens, of which the following is a specication.

My invention relates to that class of fountain-pens in which the ink iscontained in a compressible reservoir within the holder and is fed tothe pen as required by pressure upon said reservor, one object of myinvention being to construct'a simple and efficient fountain-pen of thischaracter which is adapted for use with au ordinary pen, a further object being to insure the complete discharge of the ink from thereservoir, and a still further object being to prevent the accidentaldischarge of ink when the pen is not in use. These objects I attain inthe manner hereinafter setforth, reference being had to the accompanyingdrawings, in which- Figure 1 is a perspective view of my improvedfountain-pen as it appears when in use. Fig. 2 is a longitudinalsectional view of the pen. Fig. 3 is an enlarged longitudinal section ofthe front end of the same. Fig. 4 is a transverse section on the line l2, Fig. 3; and Fig. 5 is a perspective view of the various parts of thepen detached from each other.

A is the body of the pen-holder, permanently closed at the upper end andhaving at the opposite end a plug B, which fits snugly to the body ofthe holder and serves to confine the pen as shown in Fig. 4, thatportion of the plug which actually bears upon the pen beingeccentric inrespect to the tube constituting the body, so that pens of differentsizes can be held in place by the plug, the upper portion of the penbeing always 'nipped firmly between the plug and the interior ofthetubular body, as shown in Fig. 4.

Formed in the plug B is apassage a, which at its front end is carried tothe upper face of the plug and communicates with a longitudinal channelb, through which the ink iiows to the nib of the pen.

To the inner end of the plug is secured the front end of an elasticreservoir D, which contains the supply of ink; and bearing upon one sideof this reservoir, along almost the whole length of the same, is a bard, which has .a stem f, projecting through an opening inthe body of theholder, and provided at its outer end with a head or button g, the stembeing threaded and provided with a nut h. When this nut is run down onthe stem until it bears against the body of the holder, it prevents anydepression of the stem and its bar, and thus prevents the forcing of anyink from the elastic reservoir-as, for instance, when the pen is beingcarried in the pocket. When the pen is in use, however, the nut isbacked od on the stem, so as to permit any desired extent of movement ofthe latter and its bar, and in use the penis held in the hand in suchposition thatthe button gmay be conveniently pressed'by the thumb, asshown in Fig. l, so that the elastic ink-reservoir in the handle may becompressed and the proper supply of ink fed to the pen Whenever suchsupply becomes desirable, air being drawn into the reservoir when itexpands, so as to take the place of the ink expelled therefrom'. By asuccession of operations, therefore, the entire supply of ink inthe'reservoir may be expelled, and when it is desired to reill thereservoir the latter may be iirst compressed to its full extent, so asto expel the air therefrom, and the pen then dipped in the ink and thereservoir permitted to expand, so as to draw a fresh supply of ink upinto said reservoir.

Having thus described my invention, I

claim and desire to secure by Letters Patent- 1. The combination of theholder, the elastic ink-reservoir contained therein, a presserbar havinga stem projecting through the holder, and a nut on said stem for looking the same or regulating its movement, substantially as specified.

2. The combination of the body of the holder, the pen, and the plugadapted to the body of the holder and serving to confine the pen, theconfining portion of the plug being on a curve eccentric in respect tothe body of the holder, substantially as specilied.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN RAYNALD.
